The safety signal word designates the degree or level of hazard seriousness.
DANGER: Indicates an imminently hazardous situation which, if not avoided, will result in death
or serious injury.
WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death
or serious injury.
CAUTION: Indicates a potentially hazardous situation which, if not avoided, may result in minor
or moderate injury.
CAUTION: Used without the safety alert symbol indicates a potentially hazardous situation which, if not
avoided, may result in property damage.
IMPORTANT: Important is used when action or lack of action can cause equipment failure, either
immediate or over a long period of time.
Safety Precautions
WARNING:
• The following procedures must be performed by qualified, trained personnel who
are familiar with this equipment. Operators must read and understand all safety
precautions and operating instructions included with the pump. If the operator cannot
read these instructions, operating instructions and safety precautions must be read
and discussed in the operator's native language.
• These products are designed for general use in normal environments. These products
are not designed for lifting and moving people, agri-food machinery, certain types of
mobile machinery, or in special work environments such as: explosive, flammable, or
corrosive. Only the user can decide the suitability of this product in these conditions or
extreme environments. SPX Hydraulic Technologies will supply information necessary
to help make these decisions. Consult your nearest SPX Hydraulic Technologies
facility, refer to SPX Hydraulic Technologies Facilities in this document.
• Safety glasses must be worn at all time by the operator and anyone within sight of
the unit. Additional personal protection equipment may include: face shield, goggles,
gloves, apron, hard hat, safety shoes, and hearing protection.
• The owner of this tool must ensure that safety-related decals are installed, maintained,
and replaced if they become hard to read.
• Shut OFF the motor before opening any connections in the system.
• The guide cannot cover every hazard or situation so always do the job with SAFETY
FIRST.
Pump
WARNING:
• Do not exceed the hydraulic pressure rating noted on the pump nameplate or tamper
with the internal high pressure relief valve. Creating pressure beyond rated capacities
can result in personal injury.
• Retract the system before adding fluid to prevent overfilling the pump reservoir. An
overfill can cause personal injury due to excess reservoir pressure created when
cylinders are retracted.

Form No. 1000591
Safety Precautions continued
• The load must be under operator control at all times.
• Do not connect pump to hydraulic system powered by another pump.
Electric Motor
WARNING:
• Electrical work must be performed and tested by a qualified electrician per local
directives and standards.
• Disconnect the pump from the power supply and relieve pressure before removing the
motor case cover or performing maintenance or repair.
• Check the total amperage draw for the electrical circuit you will be using. For example:
Do not connect a pump that may draw 25 amps to a 20 amp fused electrical circuit.
• Never use an ungrounded power supply with this unit.
• Changing the voltage is an involved and, if incorrectly performed, hazardous procedure.
Consult the manufacturer for specific information before attempting rewiring.
• Wire pump motors for clockwise rotation when viewed from the shaft end of the
motor.
• Do not attempt to increase the power line capacity by replacing a fuse with another
fuse of higher value. Overheating the power line may result in fire.
• Exposing electric pumps to rain or water could result in an electrical hazard.
• Avoid conditions that can cause damage to the power cord, such as abrasion, crushing,
sharp cutting edges, or corrosive environment. Damage to the power cord can cause
an electrical hazard.
Hoses
WARNING:
• Before operating the pump, tighten all hose connections using the correct tools. Do
not overtighten. Connections should be only secure and leak-free. Overtightening can
cause premature thread failure or high pressure fittings to split at pressures lower
than their rated capacities.
• Should a hydraulic hose rupture, burst, or need to be disconnected, immediately shut
off the pump and shift the system pressure manual release valve twice to release
pressure. Never attempt to grasp a leaking hose under pressure with your hands. The
force of escaping hydraulic fluid could cause serious injury.
• Do not subject the hose to potential hazard, such as fire, sharp surfaces, heavy impact,
or extreme heat or cold. Do not allow the hose to kink, twist, curl, or bend so tightly
that the fluid flow within the hose is blocked or reduced. Periodically inspect the hose
for wear, because any of these conditions can damage the hose and possibly result in
personal injury.
• Do not use the hose to move attached equipment. Stress can damage the hose and
possibly cause personal injury.
• Hose material and coupler seals must be compatible with the hydraulic fluid used.
Hoses also must not come in contact with corrosive material such as creosoteimpregnated objects and some paints. Consult the manufacturer before painting a
hose. Never paint the couplers. Hose deterioration due to corrosive materials may
result in personal injury.

Form No. 1000591
• Avoid straight line tubing connections in short runs. Straight line runs do not provide
for expansion and contraction due to pressure and/or temperature changes. See
diagrams in Initial Setup section of this form.
• Eliminate stress in the tube lines. Long tubing runs should be supported by brackets or
clips. Tubes through bulkheads must have bulkhead fittings. This makes easy removal
possible and helps support the tubing.
• Carefully inspect all hoses and fittings prior to use. Before each use, check entire hose
for cuts, leaks, abrasion or bulging of cover, or damage or movement of couplings. If
any of these conditions exist, replace the hose immediately. NEVER attempt to repair
the hose.
Cylinder
DANGER:
• Do not exceed rated capacities of the cylinders. Excess pressure may result in personal
injury.
• Avoid off-center loads that could damage the cylinder and/or cause loss of the load.
• Read and understand all safety and warning decals and instructions for devices
attached.
• Inspect each cylinder and coupler before each shift or usage to prevent unsafe
conditions from developing.
• Do not use cylinders if they are damaged, altered or in poor condition.
• Do not use cylinders with bent or damaged couplers or damaged port threads.
• Under certain conditions, the use of an extension with a hydraulic cylinder may not be
advisable and could present a dangerous condition.
• Avoid pinch points or crush points that can be created by the load or parts of the
cylinder.
• To help prevent material fatigue if the cylinder is to be used in a continuous application,
the load should not exceed 85% of the rated capacity or stroke.
• Cylinder must be on a stable base which is able to support the load while pushing or
lifting.
• To help prevent personal injury, use shims, friction material or constraints to prevent
slippage of the base or load.
• Do not set poorly-balanced or off-center loads on a cylinder.
• The load can tip or the cylinder can “kick out” and cause personal injury.
• Do not use the locking collar on a threaded piston as a stop. The threads may shear
resulting in loss of the load.
• If this component is used to lift or lower loads, be certain that the load is under operator
control at all times and that others are clear of the load.
• Do not drop the load.
• As the load is lifted, use blocking and cribbing to guard against a falling load.
• To help prevent personal injury, do not allow personnel to go under or work on a load
before it is properly cribbed or blocked. All personnel must be clear of the load before
lowering.

Form No. 1000591
• Never use extreme heat to disassemble a hydraulic cylinder or ram. Metal fatigue and/
or seal damage will result and can lead to unsafe operating conditions.
IMPORTANT
• Keep the cylinder clean at all times.
• While at a job site, when the cylinder is not in use, keep the piston rod fully retracted
and upside down.
• Always use protective covers on disconnected quick couplers.
• When mounting cylinders or rams using the internal piston rod threads, collar threads,
threaded tie rods or base mounting holes, the threads must be fully engaged. Always
use SAE grade 8 or better fasteners when attaching components to cylinders or rams
and tighten securely.
• Limiting the stroke and pressure on all cylinders will prolong their life.

Initial Setup
1.Remove all packing materials from the assembled unit.
2.Inspect the unit upon arrival. The carrier, not the manufacturer, is responsible for any damage
resulting from shipment.
Filling the Pump Reservoir
Most pumps are shipped without hydraulic fluid in the reservoir. Hydraulic fluid may have been shipped
in a separate container, but if hydraulic fluid is needed, use only approved Power Team hydraulic fluid
rated at AW 46 47 cSt @ 38°C (237 SUS @ 100°F). If low temperature requirements are needed, use
hydraulic fluid 5.1 cSt @ 100°C (451 cSt @ -40°C).
1.Clean the area around the filler cap to remove debris. Debris in the hydraulic fluid can damage the
polished surfaces and precision-fit components of this pump.
2.Remove the filler cap and insert a clean funnel with a filter.
3.Fill the reservoir with hydraulic fluid to 2.6 cm (1 in.) from the cover plate.
4.Replace the filler cap. Verify the breather-hole is open, if applicable.
Hydraulic Connections
1.Clean the areas around the fluid ports of the pump and cylinders.
2.Inspect all threads and fittings for signs of wear or damage, replace as needed.
3.Clean all hose ends, couplers or union ends.
4.Remove the dust cap from the hydraulic fluid outlets.
5.Connect the hose assembly to the hydraulic fluid outlet, and couple the hose to the cylinder.
CAUTION: To prevent personal injury from leaking hydraulic fluid, seal all hydraulic
connections with a high-quality, non-hardening, pipe thread sealant.
IMPORTANT: Sealant tape or non hardening sealer tape can be used to seal hydraulic
connections if only one layer of tape is used. Apply tape carefully, two threads back, to
prevent it from being pinched by the coupler and broken off inside the system. Loose
pieces of sealant could travel through the system and obstruct the flow of fluid or cause
jamming of precision-fit parts.
Electric Motor Operation
Warning: Electrical work must be performed and tested by a qualified electrician per local directives and standards.
The electric motor is wired for nominal 115 or nominal 230 volts, 50/60 Hz. Nominal 230 volt electric
motors are shipped without a plug attached. Please obtain and install the applicable plug for your area.

General Maintenance
WARNING:
• Disconnect the unit from the power supply before performing maintenance or repair
procedures.
• Repairs and maintenance are to be performed in a dust-free area by a qualified
technician.
System Evaluation
The components of your hydraulic system—tools, cylinders, pumps, hoses, and couplings—all must be:
• Rated for the same maximum operating pressure.
• Correctly connected.
• Compatible with the hydraulic fluid used.
A system that does not meet these requirements can fail, possibly resulting in serious injury. If you are
in doubt about the components of your hydraulic system, contact SPX Hydraulic Technologies Technical
Support.
Inspection
Keep a dated and signed inspection record of the equipment. Before each use, the operator or other
designated personnel should visually inspect for the following conditions:
• Cracked or damaged cylinder or tool.
• Excessive wear, bending, damage, or insufficient thread engagement.
• Leaking hydraulic fluid.
• Scored or damaged piston rod.
• Incorrectly functioning or damaged heads and caps.
• Loose bolts or cap screws.
• Damaged or incorrectly assembled accessory equipment.
• Modified, welded, or altered equipment.
• Bent or damaged couplers or port threads.
Periodic cleaning
WARNING: Contamination of the hydraulic fluid could cause the valve to malfunction. Loss
of the load/function or personal injury could result.
Establish a routine to keep the hydraulic system as free from debris as possible.
• Seal unused couplers with dust covers.
• Keep hose connections free of debris. Equipment attached to a cylinder must be kept clean.
• Keep the breather-hole in the filler cap clean and unobstructed.
• Use only Power Team hydraulic fluid or equivalent. Replace hydraulic fluid as recommended, or
sooner if the fluid becomes contaminated. Never exceed 300 hours of use between fluid changes.
Hydraulic Fluid Level
1.Check the fluid level in the reservoir after each 10 hours of use. The fluid level should be 2.6 cm (1
in.) from the top of the fill hole when all cylinders are retracted.
2.Drain, flush, and refill the reservoir with an approved Power Team hydraulic fluid or equivalent after
every 300 hours of use. The frequency of fluid changes depends upon general working conditions,
severity of use, the overall cleanliness and care given to the pump. Fluid should be changed more
frequently when the system is not operated regularly indoors.

Sound Reduction - Electrically Powered Motor
The electrically powered hydraulic pump operates in the 82-86 dBA range. If further sound reduction is
desired, contact SPX Power Team Hydraulic Technology technical support for products more suitable
to your application.
Hose Connections
CAUTION: Contamination of the hydraulic fluid could cause the valve to malfunction.
Loss of the load/function or personal injury could result.
IMPORTANT: Sealant tape or non-hardening sealer tape can be used to seal hydraulic
connections if only one layer of tape is used. Apply tape carefully, two threads back, to
prevent it from being pinched by the coupler and broken off inside the system. Loose
pieces of sealant could travel through the system and obstruct the flow of fluid or cause
jamming of precision-fit parts.
Storage
Store the unit in a dry, well-protected area where it will not be exposed to corrosive vapors, dust, or
other harmful elements. If a unit has been stored for an extended period of time, it must be thoroughly
inspected before it is used.
Checking Brushes on Electric Motors
To help prevent premature failure of the armature, check the brushes every 100 hours or 100,000
pressure cycles:
1.See Figure 42. Remove the brush holder caps
and brush assemblies.
Figure 42. Brush Holder Caps
2.See Figure 43. The brush assemblies must be
replaced if they are 6.35 mm (1/4") in length or
less.
Replace when

Troubleshooting Guide
WARNING:
• Repair work or troubleshooting must be performed by qualified personnel who are
trained and familiar with this equipment.
• Disconnect the power supply before removing the electrical cover. Electrical work
should be performed by a qualified electrician.
• Check for system leaks by using a hand pump to apply pressure to the suspect area.
Watch for leaking fluid and follow it back to its source. Never use your hand or other
body parts to check for a possible leak.
Notes:
• For a detailed parts list or to locate a SPX Hydraulic Technologies facility, contact your nearest SPX
Hydraulic Technologies facility, refer to SPX Hydraulic Technologies Facilities in this document.
• Plug the outlet ports of the pump when checking for leakage to determine if the leakage is in the
pump, in the cylinder, or in the tool.
